Where in the PlatformIO should these parameters for ESPtool flash upload be set?
I find it really odd that my system is apparently so messed-up right now that I cannot upload to ESP32 anymore from PlatformIO.
I tested on Atom and VScode, but both refuse to work.
So is there anything I can set in the .ini file to make it work again?

I double (triple) checked and made sure all platformio related folders are removed.
Python was already uninstalled and before uninstalling that it was stripped of any platformio installed package.
There are no platformio related settings in the environment.
I just tested with platform = espressif32@1.0.2 and @0.12.0 and last night I tested with https://github.com/platformio/platform-espressif32.git#develop

Atom has been re-installed, PlatformIO has been reinstalled many, many times.
All MS-related dev tools are removed from my system.
Latest updates are installed, just to make sure.
Curren PlatformIO version reported is: Home 0.9.6·Core 3.6.0a1
And still the same error when flashing.

With my own command to flash, I cannot flash anything built newer than @0.12.0, but that may have something to do with used offsets, partition layouts, or one of the many other new features perhaps.
It will flash, but the resulting firmware is unusable.

I’m very close to calling a format-C and reinstall my entire laptop (which will take a lot of time to setup like it should be).
